Index Contours

I have a dataset of contours at 0.5m intervals and I'd like to show an index contour every 5m. Is there a query I can use for this based on the data I have?

Thanks!

Mapping Center Answer:

We have a calculate statement for this on our ArcGIS Resources - Loadable Files page -- it is called IndexYN.

There is also a tool I wrote for Community Basemaps that does this for multiple indexes. The 10 version is at this site:

The 9.3.1 version is also at the Community Basemap Resource page under Galleries - Community Basemap Template and Tool Gallery.
